Answer:
C. Spoofing.
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
Some examples of cyber attacks are phishing, zero-day exploits, denial of service, man in the middle, cryptojacking, malware, SQL injection, spoofing etc.
Spoofing can be defined as a type of cyber attack which typically involves the deceptive creation of packets from an unknown or false source (IP address), as though it is from a known and trusted source. Thus, spoofing is mainly used for the impersonation of computer systems on a network.
Basically, the computer of an attacker or a hacker assumes false internet address during a spoofing attack so as to gain an unauthorized access to a network.

Answer:
Every Dynamic Programming problem has a schema to be followed: Show that the problem can be broken down into optimal sub-problems. Recursively define the value of the solution by expressing it in terms of optimal solutions for smaller sub-problems. Compute the value of the optimal solution in bottom-up fashion.
Python is actually an easy language to learn and use. IDLE is an iffy IDE to use. One thing about IDLE that drives me nuts is that when it saves a file, it converts tabs to spaces (you can adjust how many in the prefs). This causes impossible to find indentation errors because several spaces are NOT the same as a tab, but you can't see the difference on the screen.
# the standard way to put the main function after declaring functions and
# classes
if( __name__ == "__main__" ):
import sys
# check that the program was called with the correct number of arguments
if( len( sys.argv ) != 2 ):
sys.stderr.write( "\nusage: %s <argument>\n" % ( sys.argv[ 0 ] ) )
sys.exit( 1 )
else:
# do something nifty
sys.exit( 0 )
